Re: 1954 Evinrude 7.5hp increase power?

I see the photo on the Propco site for the prop in question – the hub looks nothing like mine – I have a rubber cone that goes over a nub on the end of the shaft and covers the shear pin at the end of the prop. The brass Michigan Wheel prop looks to be the right stuff but may be playing with fire if it is too heavy and will break my lower unit.
